The Infernal Devices is the prequel series to The Mortal Instruments by Cassandra Clare. It was the second published series in The Shadowhunter Chronicles, but is the first story chronologically.

Set in Victorian London, the series follows Tessa Gray, an orphaned teenage girl who discovers she has the power to shapeshift, abilities that plunge her into a world she never knew existed. She will have to forge an alliance with the Shadowhunters of the London Institute if she wants to survive in this dangerous world.

On April 12, 2013, months prior to the release of The Mortal Instruments: City of Bones, it was announced that a film adaptation of The Infernal Devices was in the works, with the screenplay being written by Stephanie Sanditz with a search for the director ongoing at the time,[1] though a script has been in development as early as 2011.[2] No follow-up news has been given since and the project has likely been scrapped.

Plans for a TV adaptation were made instead.[3] A writer for the pilot episode's script was assigned as early as 2017,[4] and the series was being shopped around by Constantin Film to different potential networks and distributors.[5] A report came out in May 2020 claiming that the series pilot landed at BBC Three.[6]

After the release of Clockwork Prince, Yen Press created a manga adaptation of the series with illustrator HyeKyung Baek. The series finished a year after Clockwork Princess's release and an omnibus hardback edition was published 8 years later on August 23, 2022.[7]


  • The series is very loosely modeled after A Tale of Two Cities,[8] especially Clockwork Princess, which was always meant to be a loose retelling of the book.[9]
  • The series title refers to the clockwork automatons, created by the main antagonist, which were sometimes referred to as "Infernal Devices" in the trilogy.
  • Cassandra Clare got the idea for the series while on the Blackfriars Bridge, hence the bridge's significance in the series.[10]
  • The US/Canada paperback book covers for The Infernal Devices are being updated (repackaged) and officially replaced with new ones with a more modern look, to be released in September 2015 by Simon & Schuster.[11] The covers were revealed on May 13, 2015 on[12]
  • Simon & Schuster also has further plans to do alternative "adult covers" for the series.[13][14]
